WOOL-DELIVERING DE C To all whom it may concern: i

Be it known that I, EDwARnP. OBRIEN, a citizen of the United States, residing at East Weymouth, in the county ofNorfolk and State of Massachusetts, have'invented 'new and useful'lmprovements in Wool- De livering Devices, of which "the following 1s a specification. I

T his'inven tion relates to a device for delivering the wool to the feeders of wool scouring machines, and its object is to provide a device whereby an even and regulated supply of wool'to the feeder maybe secured, thus obviating the known objections tothe irregularities of hand feeding while enabling a single attendant to control the supply of woolto aplurality of feeders.

A further object of the invention is to provide a delivery means whereby the wool may be delivered fast or sloW according to the character of the wool or running speed or capacitv of the feeder, so as to secure a regular and even feed whilch'is essential to the efiicient action of the scouring machine.

The invention consists of the features of construction, combination and arrangement of parts herein fully described and claimed,

reference being had to the accompanying drawings in which I Figure 1 is a front elevation of a feeder and wool chute, the door of the chute being thrown open, showing the application of the invention thereto. Fig. 2 is a side elevation of the same. Fig; 3 is affront; to rear section. Fig. 4 is a sectionalplan view on line 4: l of Fig. 3. Fig. '5 is a fragmentary view looking toward the opposite side of the chute fromthatshown in Fig. 2, and

showing the controlling lever, a portion of the chute being broken away to show the' table and reel. Fig. 6 is'a'frag'mentary perspective view ofthe adjustable feed regulate" ing table. Fig. 7 is a detail section on the line 7-7 of Fig. 2. Fig. 8 is'a detail section on line 88 0f Flg. 5. Fig. 9 is a'detail section on the line"99 of Fig. 2. ,7

" Referring to the drawings, 1 designates a wool feeder of known type, which is supplied, as usual,,with wool for delivering to the scouring mechanism by means of a chute 2, In modern I scouring. plants. .the scouring machinesand feeders are generally arranged Specification of Letter s iatent.

Ordinarily an attendantis required for manuallyfdelivering the Wool contained in the chute to the feeder, great care and exactness 7 in feeding the wool be in g necessary inorder to avoid poor or uneven work, uniformand even feeding being absolutely essentialin woolscouring- Asa result, through carelessness or inefficiency, "a great deal of poor I or improperworlr 1s done, andan attendant must beemployed for supplying each feeder,

a source of'considerable expense in'large plants;

.;My'inve'ntion provides delivery mechanisrn' which overcomesrthe'se objections, and which insures absolutelys'mooth and even feeding of a character suited both to the Wool: and action ofthe scouring machine,

and which at the "same time obviates the necessity of-employing'an attendant for each feeder and chute, a. single attendantbeing able to take care of a number'of'feeders operating at the same time.

- In carrying myl'inventlon' into practice, I

provide within the chute 2, at a point about inline with the' door 3 thereof, an adjustable feed regulating table 4',which table is d esigned to support the body of wool co ntained within'the chute and comprises an imperforate body ,portion" provided with operating beneath theslatted ta'ble, and the teeth ofthewheels or disks of which are} adapted: togpass through or work inclose!" contiguity to the slotsbetwe'en 'the'slats 5' and to rake through and draw downpar ticles of ;the "woolexposed 'therethrough,

which "are thereby supplied to the feederL for conveyance to the scouring machine." By I adjusting the table, so that the slatted por ti'on thereof will lie closer to or farther from the teeth or the wheel disks a is evident that the amount of wool taken up or gathered by the disks may be varied according to the speed or scouring capacity of the mill and to the grade or character of wool which is being supplied'thereto to be scoured.

Intermittent feed mechanism for actuating the reel is provided and comprises a wheel or disk 8 fixed to one end of theshaft 6 and which is provided with a wrist pin 9 to which is coupled one end of a pitman 10, the opposite end of which is coupled to a wrist or crank pin 11 carried by a block 12 slidably engaging a slot 13 in a crank arm 14 projecting from a crank head or disk 15. This head or disk 15 is secured to one end of a horizontal transverse drive shaft 16, which may be driven from 'anv suitable'source of power and provided with a drive pulley or gear element of a'suitable character for that purpose. 7 I

The block 12 is adapted to be adjustably secured in position at any point along the length of the slot 13 by suitable fastening means. such asa screw stem 12 integral with the-block, together with a washer 12 and nut 12, the lever; 10 being held in engagement with the wristror crank pin 11 by a cotter pin 11 In the rotation of the shaft 16 the crank arm 14 transmits motion to the crank disk 8 through the pitman 10 and crank pin 9, and bv adjusting the block 12 and wrist pin 11 along the slot 13 it will be evident that the effective radius and stroke of the crank arm 14 may be varied to correspondinglv vary the degree of motion of the rotating d sk 8, as will be readily understood. 'Fulcrumed upon the disk 8, which 7 is loosely mounted on the shaft 6, is a dog or pawl 17 adapted to engage the teeth of a ratchet wheel 18 fixed to the shaft 6. so that on the working motion of the disk 8 the dog will contact with the shoulder of one tooth and move the ratchet wheel, disk and rail a predetermined distance or portion of a revolution while on the return motion of said disk the dog will slide over the inclined faces of the teeth and be reset for a subsequent feed action. The slats or fingers 50f the table 4 are secured to bracketlugs 19 provided with sleeves 20 having angular bores for the passage ofa rock shaft 21 and secured to said shaft bv screws or other like fastenings 22. The ends of the shaft 21 are fitted in collars 23 journaled in bearings 24 in the side walls of the chute. A cotter pin or key passes through one end of the shaft and holds thesame against longitudinal d splacement, while the other end of the shaft is connected with the upper end of a controlling lever 26, said lever being provided with a longitudinal slot 27, for the passage of the threaded stem 28 of a headed guide and pivot pin 29, theheaded end of which is fitted to slide in a slotted guide bracket 30, the parts being held againstv adapt the lever to be adjusted to rock the shaft and-secure it in adjustedposition by tightening the nut 31 to clamp the head of the screw 30 against the slotted wall of the guideway, the screw sliding longitudinally of the lever to compensate for the variations in the arcs of movement of the pivoted por tion of the lever and the end thereof connected with the rock shaft. When the table is raised the bulk of the wool resting thereon is held to a'greater or less extent out of the path of movement of the teeth of the wheel 7, so that a relatively small'amount ofwool will be supplied to the feeder, while by lowering the table an extent of projection of the teeth of the wheel 7 through the spaces between the table fingers will be increased, allowing the toothed wheels to draw down a greater amount of wool, so

' that the supply of the wool to the feeder tion of the delivery reel may be varied for a complemental action of the table accord ing to the position of the latter-and the speed of action of the scouring machine, so that the apparatus may be set as conditions may require to handle anv kind of wool according to go erning conditions and to deliver wool with a mathematical exact and even regulated rate of speed. so that the exact amount'of wool for a proper scouring action and no more will be delivered. As a result greater efliciencv of action of the seourer is obtained, while the use of the delivery device obviates the necessity of employing an attendant for each feeder, a single attendant being enabled to handle a number of feeders. with a consequent reduction of expense to'the establishment.
